public class singleLink
extends javax.swing.JPanel

Represents a link between two operators. Displayed on the screen as a JPanel added to the panel on the scrollpane, filling it entirely but transparent so other compoents (other links and operatorBoxes can be seen beneath it. A link exists between a specific output (1 or 2) of an operator and a specific input (1 or 2) of another operator. Only one single link can link to a specific input. Several links can link from an output.
